Mechanism and disaster control new technology of strong ground pressure manifestation in ultra‐large mining face

Deep Underground Science and Engineering, EarlyView.
In response to the problem of strong mining pressure manifestation along the goaf roadway in a thick coal seam mining area, this study uses a new type of combined blasting roof cutting technology to effectively control the manifestation and deformation of mining pressure along the goaf roadway.

Composite concrete columns of 3DP concrete and self-compacting concrete subjected to normal force [PDF]

Conventional concrete columns are cast in forms made of steel or wood. The work of erecting and dismantling the formwork is time-consuming and laborious. Steel forms can be used several times but wood forms are usually only used once or a small number of

Investigation on the mechanical behavior of the multiple‐layered lining structure of a water conveyance tunnel with high internal water pressure

Deep Underground Science and Engineering, EarlyView.
This study presents large‐scale similarity model testing (geometric ratio 3.6) of an innovative multiple‐layered lining system—comprising exterior precast segments, middle self‐compacting concrete, and an interior steel pipe—for high‐pressure (0.75 MPa) water conveyance tunnels.

A Mixed‐Ligand Metal–Organic Framework Strategy to Construct High‐Density O/S‐Shelled Ag Nanoparticle Electrocatalysts for Syngas Modulation

EcoEnergy, EarlyView.
Mixed‐ligand Ag–triazole MOF precursors reconstruct into ligand‐shelled Ag nanoparticle electrocatalysts that retain detectable O/S‐derived interfacial species. By combining ligand‐ratio and potential control, the CO2‐to‐syngas output can be tuned across H2‐rich, near‐equimolar, and CO‐rich regimes.

The Influence of Construction Joints on the Shear Behavior of Reinforced Self-Compacting Concrete Beams

Tikrit Journal of Engineering Sciences
Construction joints are essential in massive concrete structures since these structures cannot be cast in a single pour. Nowadays, Self-compacting concrete is preferred due to its ability to compact without vibration and segregation concerns.
